Specification of Letters Patent.

Application led September 28, 1916. Serial No. 122,618.

To all whom t may concern.'

Be it known that I, PARKE T. SNYDER, a citizen of the United States,residing at Chicago, in the county of' Cook and State of Illinois, haveinvented certain new and useful Improvements in Demountable-Wheels, ofwhich the following is a specification.

This invention relates to improvements in vehicle wheels and moreparticularly to a demountable wheel for motor cars.

One of the great difficulties encountered in motoring is the delay andannoyance caused by injury to the pneumatic tires, resulting frompunctures or blow-outs. Before the advent of the demountable rim anddemountable wheel, it was necessary forthe motorist, in the event of apuncture or blow-out, to remove the casing fromthe rim and replace orrepair the inner tube, a most difficult and time consuming operation,when remote from a garage where the proper tools may bevobtained andwhere air is usually stored underpressure for inflating the tire.l

Since the introduction ofthe now, well known demountable rims anddemountable wheels, the above referred to annoyance has been eliminated,motorists carrying with them a spa're tire, already inflated, in thefirst instance on a detachable rim and in the second instance on adetachable wheel, which may be used to replace the injured tire.

One of the objects of my invention is to provide a demountable wheelwhich may be j removed and replaced by a spare wheel carrying aninflated tire in a minimum amount of time, without difficulty orannoyance.

Another object of the invention is to provide a demountable wheel ofsturdy and rigid construction which will not get out of alinement orloose in its spoke joints.

Another object of my invention is to provide such a Wheel which may bereadily attached to Ford automobiles, combining efficiency and greatstrength, with low manufacturing cost. Y

Still other and further objects will bef come readily apparent to those`skilled in the art from a consideration of the following specificationand drawing, wherein Figure l is a fragmentary sideelevation of myimproved demountable wheel showing the hub construction.

' Fig. 2 is a vertical sectional View through the center of my improvedhub, and;

Fig.- 3 is a fragmentary sectional view 4through a modifiedboltconstruction.`

Referring to the drawings, wherein I have illustrated a preferredembodiment of my invention, the numeral 10 4indicates a vehicle hub,within which the usual annular bearings are carried.k rEhe spokes of myimi proved wheel may be joined by any of the well known methods, theform illustrated comprising a plurality of spokes 11, the inner endsl2,of which are beveled to coact and form a complete disk, the inner andouter faces of which are overlain by annular metal plates 13, 14.

The plates and wheel hub'are bored at spaced apart intervals to receivetubular bushingsl, the inner ends of the bushings 15 being flanged over,as at 116, to-lie within the countersunk openings 17 in ythe' innerplate; The outer ends of the .bushings 15 are Screw threaded, as at 18,for engagement by nuts 19, which clamp the tubes in place, thusvsecurely fastening together the two plates with' the interpositionedlspokes.

lThe structure thus far described, therefore,

mountable wheel abuts. Projecting outwardly from the plate 20 are aseries of' studs 21, in screw threaded engagement, as at 22, with theplate 20, the inner ends being provided with heads 23, and the outerends threaded, as at 24. The studs 21 are of adiameter such as to make'a-comparatively tight fit'with the interior diameter of the bushings 15and cap nuts 25 are 'screw threaded on the outer ends of the studs 21 toclamp the wheel in place.

The hub 10 is provided with a flat shoulder 10 of'an axial widthsufficient to provide ample bearing for the demountable wheel and theouter plate 14 is flanged outwardly at its center 26 tov provideadditional bearing upon the shoulder 10.

A. modified form of this construction is shown in. Fig. 3, in which thetubular-basi ing 1.5 is screw threaded at its inner end 16 forengagement with the threaded opening 17T in the inner plate 13. Theouter end of the bushing 15 is screw threaded, as at 18, asin the firstdescribed embodiment of the invention and a nut 19 in `engagementwiththescrew threads 18 clamps the two plates and spokes in rigid relationship.In this'modiied form the stud 21 is reduced in diameter and screwthreaded at e 22, for engagement with the screw threaded opening lin theplate 20 and a cap nut 25 makes engagement with the threaded end 24, asin the first scribed construction.

' From the above yit is obvious that I have provided a demountable wheelin which the spokes are rigidly secured in position by a pair of plateson opposite sides by means of tubular bushings which` clamp the twoplates together and the wheel is secured to the hub by means of studscarried by the hub and arranged for insertion within the openings in thetubular bushings. In this manner I have been able to reduce the numberof fastening bolts to a minimum, say 6, for example, as illustrated inthe embodiment shown in the drawings and the same number' of holes aremade through the spokes, since these holes serve not onlyto receive'thespoke clampingv members, but

fr also the wheel clamping members,

Whereas I have illustrated and described a preferred embodiment with asingle modication thereof, it will be obvious to those skilled in theart that various modifications tubes extending through openings in the`plates and spokes, onevend being formed for engagement with one plateand the other end being threaded, nuts on the threaded ends of the tubesfor clamping the plates and spokes in rigid relationship, studs carriedby the hub and arranged for insertion through the tubes, and nuts forengagement with the outer ends of the studs for ing the wheel to thehub.

'In'test' ionyv whereof I hereunto set my hand in stieg, presence of twosubscribing RARKE T. SNYDER. In the presence of- STANLEY W. COOK, MARYF. ALLEN.
